31ENCount function (No.11 COUNT-FNC)You can count the screw fastening number, and judge operations OK. In addition, you can use the workpiece signal(workpiece detection sensor) to judge operations NG.CAUTIONzz When the “operations channel switching method” (No.1 CH-CHG) is “S-AUTO” or “C-AUTO”, the count functionjumps to the “OFF” operations channel.In addition, if the count function of any of the channels is not set to “ON”, LCD is displayed as shown below, andthe setting mode cannot be ended.zz If a workpiece signal is not used, the operations NG judgment (NG output signal ON) cannot be performed.To improve screw fastening operations control and quality, use of the count function and workpiece signal isrecommended. By setting the count function to “ON”, you can perform settings for the setting items No.12 to 21.Workpiece signal (No.12 WORK-SNSR)Sets whether you use the workpiece signal (workpiece detection sensor) or not.Setting MotionOFFzz Electric screwdriver can be constantly activated, for automatic screw fastening operations startzz After screw fastening operation is completed, OK is activated for 0.3 seconds after “screw fasteningconfirmation time” (No.17 OK-OUT-T) has elapsed, and automatically switches to the next operations channel(OK output timing is same action as 'C-F' setting)zz Operations NG cannot be judgedONzz Electric screwdriver activates only when workpiece signal has been input (prevention of inadvertent operation)zz If the workpiece signal input is set to OFF when the screw fastening operation is not yet completed (countnumber still remains), operations NG is output (in this case, the workpiece signal input is again set to ON,and the screw fastening operation is restarted, or the operations NG is released by WORK RESET, and theworkpiece is moved to line-out)For the workpiece signal (workpiece detection sensor) wiring, see “Using the workpiece signal” (p. 42).CAUTIONzz To improve screw fastening operations control and quality, use of the count function and workpiece signal isrecommended.Count number (No.13 COUNT)Sets the screw count at 1 to 99.The count number displayed in the controller [COUNT] LED during screw fastening mode is the countdown method.Workpiece setup time (No.14 WORK-S-T)Sets the time from setting up the workpiece (workpiece signal input ON " [WORK] LED flashing) to the electricscrewdriver action being enabled ([WORK] LED lighted) at 0.0 to 9.9 seconds.Within this time period, the electric screwdriver does not activate (rotate), and even if workpiece signal input ON/OFFrepeatedly occurs due to workpiece removal, position adjustment, or redo, etc., operations NG does not occur.
